The suitable DC process group being used together with system 40 (and other) and the example of pointer array exist It is described in detail (seeing part 3-5) further below.Embodiment described in part 3-5 includes being configured The certain illustrative becoming to produce the different information of the vibration stood by main frame or the display of different aspect is arranged.

Part 3:

As illustrated in figures 4-5, this section describes and be suitable for monitoring system (such as system 20 and/or be at Passive vibration System 40) " accumulation " version in use parts and subsystem.DC process group 150 is described above DC processes the embodiment of the one or more parts in part 78 and visual display portion 96.Similarly, depending on Feel that display part 200 is the embodiment of visual display portion 96 as above.Therefore, similar parts can To use similar reference to carry out labelling.

Fig. 4 is to illustrate that the illustrative resistor being suitable in accumulation vibration monitor system using and indicator are arranged Circuit diagram.DC process group 150 includes being configured to receive from filtering part (such as, filtering part 50) DC signal 152 and produce any suitable layout of parts of array or the network of output energy.Output The array of energy is configured to produce in the visual state of the array of the connection of indicator component persistently change, The described vibrational energy persistently changed corresponding to the accumulation sensed by the transducer being associated.

Such as, receive DC signal 152 in response to one or more process groups and produce the array of output energy, Vision element 170-176 can be configured to respond to wherein to export process group 150 defeated exceeding energy threshold Go out energy and continue visual state from first and change over the second lasting visual state.In the exemplary embodiment, Corresponding to multiple vision element 170-176 of amplitude of the first output at the corresponding threshold beyond each vision element Can change during value level and continue visual state to second, thereby indicate that the peak vibration sensed by transducer Level.

The persistent state of First look indicator changes the amplitude that can correspond to output, and array can wrap Including the first and second visual detectors, the most each visual detector has two and continues visual state or two Energy threshold level.In one exemplary embodiment, described array can include one group of visual detector, institute State one group of visual detector to be arranged (such as, with adjusting to a line) and make a part for this group visual detector Can change to the second visual perseveration state from First look persistent state, thus provide and sense with by transducer To frequency band or the visually indicating of the peak vibration energy level that is associated of scope.By this way, for many The visual detector (such as, with adjusting to a line) each with one group of layout in individual array, often organizes vision A part for indicator can change to the second visual perseveration state from First look persistent state, with provide by Visually indicating of each peak vibration energy level in multiple component bands that transducer senses.

Therefore, the system including DC process group 150 is display configured to be stood by monitored main process equipment Accumulation vibrational energy.In order to realize this function, DC process group 150 includes the network of resistive stacking.At figure In the illustrated examples described in 4, four such stackings (154-160) are organized in parallel with each other. Other suitably layout of parts can be used to similar effect with network.

Each resistive stacking includes one or more resistance element (such as, resistor).In showing that Fig. 4 describes In example, it is shown that each stacking there is single representative resistor, be called resistor 162-168.But, More or less of resistor can be used in each stacking.

In this illustration, (such as, resistor 162-168 each can have different resistance values Measure with ohm).Such as, resistor 162 can have the resistance lower than resistor 164, resistor 164 Can have the resistance lower than resistor 166, resistor 166 and then can have than resistor 168 more Low resistance.Therefore, stacking 154-160 can be arranged with the order of resistance that reduces from top to bottom.

Each stacking of resistive stacking 154-160 may be connected to corresponding vision element 170-176 (also referred to as For visual detector and/or visual detector element).These elements are collectively referred to as the battle array of vision element 170-176 Row 178.In this example, each vision element is configured to gradually and constantly change its visual state.Example As, vision element can be dumped to described element along with electric energy and change into from incandescent very dark.In described unit After part receives the electric energy of certain cumulant, it is possible to achieve be transformed into very dark state.

When DC signal 152 processed group 150 reception, all vision element 170-176 all experience certain journey The state of degree changes (such as, damage or deteriorate).But, due to the resistance value of the reduction in stacking, relatively low Vision element will stand more energy and change visual state more than higher elements.Due to higher Resistance value, have less electric current to flow through indicator.Vision element will be had by DC signal 152 subsequently Similar effect, this depends on signal intensity and/or persistent period.

Due to the staggered resistance value of stacking, lower visual detector (such as) than on visual detector less After exposure, will proceed to secretly from bright.Such as, in order to change completely between the extreme value of visual state, element The amount (with the form of DC signal 152) of the accumulation input energy that 172 can need is the tired of element 170 needs Three times of the amount of long-pending input energy.Similar relation may reside between remaining element, wherein difference by The resistance value of the selection of each stacking determines.Staggered resistor network allows signal and all visual detector phases Interaction, to change degree, produces the instruction of cumulative exposure.During the longest one section of low-down amplitude signal Between whole visual exposure frequency band will be made saturated such as shorter, high-intensity signal.

The corresponding array 178 of DC process group 150 and vision element 170-176 is associated with single component bands. Therefore, array 178 is displayed on this frequency band the cumulant exposed.Additional DC process group and corresponding regarding Feel that array is displayed for the impact on multiple frequency bands.Each visual array in these type of visual array multiple Any an appropriate number of vision element can be included.Similarly, any an appropriate number of visual array can be by It is included in integral display.
